Purpose
The DIR mapping tool enables you to standardize exam names by mapping to the most closely associated Radlex Playbook IDs (RPIDs) for CT exams or ACR Common procedure names for fluoroscopy procedures and digital radiography exams (grouped as projection X-ray exams). The tool is best used for mapping one or several exams or procedures. If you need to map many exams--especially if you are just getting started--check out the Knowledge Base article Using the Mapping Tool's Export and Update Features.
Process Overview
About Mapping CT Exams
Mapping an exam name to a Radlex Playbook ID (RPID) involves the steps described below and presented in the screenshot. The numbers on the screenshot correspond to each step.
Select an exam from the list of your exams by clicking the box to the left of the exam description
Click the Search RPID button to open the Search RPID dialog box that enables searching for exams by various characteristics, e.g., Body Region, and associated values.
You can also search by RPID code and RadLex Playbook exam name short descriptions. The percent sign is accepted as a wildcard character.
Click the Search button to review the list of RPIDs returned, and select the most appropriate one
Click Assign RPID.
Note: In step 1, you can select one or more closely related exams to map to the same RPID or ACR Common Procedure.
If the value in the RPID Shortname column is an insufficient explanation for the exam, go to the RadLex website and search for the RPID Longname by selecting the Download link in the upper top right corner of the screen to generate an Excel file of all available names. Similarly, for fluoroscopy and digital radiography exams use the ACR’s interactive tool to navigate the complete listing of available ACR Common Procedures.
Step-by-Step Example: Assign an RPID to a CT Study Description
Suppose you wish to map the exam name CT ABD PEL WWO IV CON to an RPID.
1. Check the box next to that exam name, and then click the Search RPID button.
The Search RPID pop-up window appears.
2. Select the appropriate categories to search for possible RadLex Playbook exam IDs and descriptions. For example, suppose the exam should be assigned to CT ABD PELVIS WO & W IVCON. Under Body Region, check Abdomen and then Pelvis, and for Contrast Enhancement select Without then With IV Contrast from the drop-down menus. You also can search by RPID code and RadLex Playbook exam name short descriptions. e.g. CT ABD PEL. Click the Search button to query for possible exams.
The list of RPID exams narrows down to Shortnames matching your criteria.
3. Select RPID198 by clicking the radio button next to it
4. Then click the Assign RPID button.
The mapping is assigned to the study description and the status is updated to Tagging Completed. To verify the description was assigned correctly, choose Tagging Completed from the drop-down menu next to the Status button, and look for the exam in the list of Tagging Completed exams.
About Mapping Fluoroscopy and Digital Radiography Exams
Mapping to ACR Common Procedures follows the same basic process with some minor differences in labels – e.g. the Search RPID button for CT exams is labeled Search by Common Procedure for fluoroscopy and digital radiography.
